SWITCHING REGULATORS |
摘要 |
A switching regulator switches a current from input direct current (DC) power to generate target DC power. The switching regulator includes: a direct current (DC)-DC converter and a ripple injection circuit. The DC-DC converter is configured to: generate an output voltage at an output terminal based on an input voltage applied to an input terminal, and according to a switching cycle that selectively forms a voltage-down current path or a voltage-up current path based on a comparison between a reference voltage and a voltage sensed at a feedback node; and apply a feedback current from the output terminal to the feedback node. The ripple injection circuit is configured to: generate a pulse current synchronized with the switching cycle; and apply the pulse current to the feedback node. |

1. A switching regulator comprising:
a direct current (DC)-DC converter configured to,
generate an output voltage at an output terminal based on an input voltage applied to an input terminal, and according to a switching cycle that selectively forms a voltage-down current path or a voltage-up current path based on a comparison between a reference voltage and a voltage sensed at a feedback node, andapply a feedback current from the output terminal to the feedback node; and a ripple injection circuit configured to,
generate a pulse current synchronized with the switching cycle, andapply the pulse current to the feedback node. |
